METALLIC DOOR-MAT.

SPECIFICATION forming part of Letters Patent No. 421,040, dated February11, 1890.

Application filed January 18, 1889. Serial No. 296 ,72 6. (No model.)

it appertains to make and use the same.

This invention comprises improvements in the form or contrivance of themetallic strips of which the mat is made to facilitate the scraping ofmud from the shoes and to prevent slipping on the mat, also improvementsin the manner of uniting and securing the strips together in the mat,allV as hereinafter described, reference being made to the accompanyingdrawings, in which- Figure l is a side elevation of a portion of a stripsuch as we provide for our improved mat. Fig. 2 is a plan View of asection out of a corner of our improved mat, these two views being aboutfull size. Fig. 3 is a longitudinal sectional elevation of the mat on asmaller scale, and Fig. 4 is a plan view of a complete mat on a stillsmaller scale.

Ve take metallic strips a, of approved width and thickness, the samebeing about as represented in Figs. l and 2, but variable, ascircumstances may require, and make V-shaped notches b, having roundedor convex sides, as shown, at intervals along each edge alternately, andbeing of suitable depth to form scrapers for the edges of theshoe-soles, the strips being so placed together in the mat that thenotches of all the strips lyingin one and the same direction come inlines transversely to the strips, forming channels or grooves across themat, and also so that these grooves or channels are located midway, orthereabout, between the strips lying in the same direction with them.The notches b are also useful to prevent slipping sidewise, and for thispurpose are alike useful, whether arranged in line, as described, forthe scrapergrooves or not, and when used for this purpose only we do notlimit ourselves to the alignment ofthe said notches. Ve also in somecases crimp these strips sidewise in short and rather abrupt crimps oftwo or more crimps to the mesh of the completed mat, as shown, or tothedistance of the strips apart suited to prevent slipping lengthwise ofthe strips when snow and ice adhere to the soles of the shoes, and thennotching them, as at c, suitable for halving them together cross- Wiseand edgewise. As is common in the making of mats of strips of any kind,we set up the slats comprising the web and secure them in a frameconsisting of the bindingstrip d, which may have notches b or not, aspreferred, by bending the ends f parallel to and so as to bear on theinside of the bindingstrip, and riveting said ends thereto, as at e. Itwill be seen that with these scraper-notches rounded or convexed, so asnot to form angles that would cut the shoes, and arranged in linespractically7 constituting grooves in the face of the mat, very efficientscrapers are produced for cleaning the edges of the shoesoles by turningthe feet sidewise, so as to run the edges of the shoes along thegrooves, and

the short and abrupt crimps, such as we represent, are adapted toprevent slipping lengthwise along the strips, which is very liable whenthe strips are straight, and even Where the strips are made with longparallel corrugations, as they sometimes are.

It is better for preventing slipping that the crimps of the differentstrips are not parallel, and we prefer to so arrang'e them; but, beingshort, they are effective either way, and they are also useful in matshaving strips arranged in only one direction.

Te arrange the strips in the mat irrespectively as to the order of thecrim ps of the respective strips-that is, whether the crimps comeparallel or not. For example, as in Fig. 2, in which the crimps areparallel in the strips of one direction and are reverse to each other inthe strips of the other direction.

' Our mat is reversible and alike useful either side up, the stripsAbeing notched in both edges; but of course the strips may only benot-ched on one edge, if so desired. The manner of fastening the web ofthe inner part to the binding-frame is alike useful for strips of anyform, and however interwoven or crossed, and whether made withscrapernotches and crimped or not, and is very simple, and enables theassembling and securing the parts with very little care and trouble.

ICO

lVha-t We claim, and desire to secure by Letters Patent, is-

1. A strip for metallic mats, said mats coniposed of two series of plainflat parallel strips crossing each other at right angles and being setup edgewise` said strip consisting of a plain fiat strip having notchesin one edge for connection with the crossing-strips, and also notches inone or both edges intermediate to said notches for the crossing-strips,substantially as described.

2. A niat made of nietallic strips set edge Wise upward and havin gnotches with rounded corners in the edge or edges, substantially asdescribed.

3. A mat inade of metallic strips set edge- Wise upward and havingnotches Wi th rounded corners in the edges alternately along the saine,substantially as described.

4. A mat made of metallic strips set edgewise upward andhavingserapennotches with rounded or convex sides in the edges andarranged in line,for1ning scraper-grooves in the .tace of the mat,substantially as described.

5. A mat composed of metallic strips set edgewise side by side and beingcorrugated sidewise with short abruptcrinips adapted to prevent slippinglengthwise on the strip and placed irrespectively as to the order of thecrinips of the respective strips.

G. A mat inade of longitudinal and cross metallic strips set edgewiseupward and having scraper-notches with rounded or convex sides in theedges and arranged in lines forining scrapergrooves in the face of themat, and also having two or niore short abrupt sidewise criinps to themesh of the crossstrips or to the distance of the parallel strips apart,substantially as described.

In testimony whereof We aiiix our signatures in presence ot' twoWitnesses.
